  • 12-point drive engages fasteners securely

17 mm 12-point insulated combination wrench

The Gray Tools MEB17-I is a 17 mm combination wrench with a 12-point drive for secure fastener engagement. It is insulated to protect the user up to 1000 V and individually tested to ASTM F1505 standards. An orange outer layer and yellow inner layer provide a visual safety indicator for insulation integrity. Electricians and technicians working on live low-voltage equipment will find this tool suited to their needs.

Who this suits and who it does not

This wrench suits professionals requiring a single 17 mm insulated spanner for electrical maintenance and repair tasks. It does not suit buyers who need a full set of insulated wrenches or multiple hex sizes for varied fastener dimensions. Users working on de-energised systems without voltage exposure requirements can select non-insulated alternatives. The tool is not designed for high-torque impact applications.

1000 V insulation rating per ASTM F1505

The defining specification is the 1000 V insulation rating verified by individual testing to ASTM F1505. This confirms the wrench meets the safety standard for live electrical work up to that voltage. The dual-layer insulation with a yellow indicator layer allows quick visual checks before each use. If your application demands a different voltage rating or a different hex size, this model will not meet the requirement.

Questions about this item

What size fastener does the 17 mm hex on this wrench fit?

The 17 mm hex opening fits metric fasteners with a 17 mm across-flats dimension.

Will the 12-point drive engage bolts that have worn or rounded corners?

Yes, the 12-point drive contacts the flats rather than the corners, so it can turn mildly rounded 17 mm fasteners.

How do I confirm the insulation is still intact before each use?

Check that the outer orange layer shows no cuts and the inner yellow layer is not visible; the yellow layer is the visual safety indicator.
